Description
Technical Field
[0001] The invention belongs to the technical field of sewage treatment, and specifically relates to a device and method for electrocatalytic oxidation treatment of high-salt industrial wastewater. Background Art
[0002] High-salt industrial wastewater contains a large amount of salt and organic pollutants. Traditional treatment methods are difficult to effectively remove pollutants and the treatment cost is high. Electrocatalytic oxidation technology has broad application prospects in the treatment of high-salt industrial wastewater due to its advantages such as high efficiency and environmental protection. Electrocatalytic oxidation technology consists of a complete current circuit consisting of a power source, anode and cathode, and a catalyst. The air produces hydroxyl radical intermediates under the action of electric current, and the free radical intermediates react with the organic pollutants in the wastewater as the main oxidant to purify the wastewater. The electrocatalytic oxidation technology for wastewater treatment has multiple functions such as oxidation, reduction, neutralization, and coagulation, and can be applied to a variety of difficult-to-treat wastewaters.

[0026] A rotating groove is provided at the position where the sleeve 301 and the liquid extraction tube 302 are connected, an assembly hole is provided at the position where the body 101 and the liquid extraction tube 302 are connected, and the liquid inlet tube 303 is fixedly arranged on the partition 102, and the liquid inlet tube 303 is arranged between the electrode assembly 106 and the sleeve 301.
[0027] A through groove is provided on the surface of the sleeve 301 , and a baffle 3012 is arranged inside the through groove. A spring is provided on the surface of the baffle 3012 , and a positioning plate 3011 is provided on one end of the spring away from the baffle 3012 . The positioning plate 3011 is fixedly arranged on the surface of the sleeve 301 .
[0028] An adjustment component is provided on the surface of the sleeve 301, and the adjustment component includes a support plate 305, the support plate 305 is provided on the outer surface of the sleeve 301, and the outer surface of the sleeve 301 is provided with a collection frame 308 adapted to the support plate 305, and a hydraulic rod 306 is provided at one end of the support plate 305 away from the sleeve 301, and a movable plate 307 is provided at one end of the hydraulic rod 306 away from the support plate 305, and push plates 309 are provided at both ends of the movable plate 307. Under the action of the hydraulic rod 306, the support plate 305 drives the push plate 309 to squeeze the baffle 3012, so that the baffle 3012 is misaligned with the through groove on the sleeve 301.
[0029] During use, it was found that due to the presence of more impurities in the wastewater, the impurities are easily attached to the surface of the electrode assembly 106, and a covering layer is formed on the surface of the electrode assembly 106 for a long time, which hinders the contact between the electrode assembly 106 and the wastewater, and reduces the activity and reaction efficiency of the electrode assembly 106; and because the bubbles are not fully combined with the suspended matter in the wastewater, part of the suspended matter is deposited at the bottom of the body 101, thereby affecting the impurity removal effect of the wastewater.
[0030] When in use, the interior of the body 101 is divided into an electrolytic cell and an air flotation tank by setting a partition 102, and then the wastewater to be treated is introduced into the interior of the reaction component 1, and the wastewater is electrolyzed by the electrode component 106. The cathode electrode plate in the electrode component 106 is the cathode, and the anode electrode plate in the electrode component 106 is the anode. The wastewater generates a large number of tiny hydrogen bubbles in the cathode state. The diameter of the hydrogen bubbles is generally 18 to 90 microns, which plays the role of an air flotation aid. At the same time, the hydroxide ionized in the anode state plays the role of a coagulant, which helps the impurities in the wastewater to float. Under the action of the water flow, the wastewater in the electrolytic cell enters the air flotation tank through the guide component 3, and then the suspended matter in the wastewater adheres to the microbubbles, floats to the liquid surface with the bubbles and forms a scum layer, and then the scum on the liquid surface is cleaned by the scraper 4, thereby separating the impurities in the wastewater, thereby achieving the effect of purifying the wastewater.
[0031] In order to improve the reaction effect, the gas in the dissolved gas tank 201 is transported to the dissolved gas releaser 203 through the gas delivery pipe 202. Under the action of the dissolved gas releaser 203, the released gas will form tiny bubbles, which float up and pass through the electrode assembly 106, thereby combining with the impurities on the surface of the electrode assembly 106 and floating up, thereby reducing the impurities adhering to the surface of the electrode assembly 106. In the initial state, the controller controls and adjusts the working state of the adjustment components on the surface of the sleeve 301 respectively. Specifically, the controller controls the hydraulic rod 306 to contract, and the hydraulic rod 306 drives the movable plate 307 and the push plate 309 to squeeze the baffle 3012. In this process, the spring is stretched, the baffle 3012 is misaligned with the through slot on the sleeve 301, and at this time, the movable plate 307 and the collection frame 308 are spaced apart. There is a gap, and it is not in a sealed state. Turn on the water pump, and under the action of the water pump, the liquid extraction pipe 302 is sucked, so that the wastewater with bubbles in the electrolytic cell enters the interior of the sleeve 301 through the liquid inlet pipe 303, and the rotating blade 3042 rotates under the action of water force, and then the rotating blade 3042 drives the driving shaft 3041, the fixing frame 3043 and the sleeve 301 to rotate together. During the rotation of the sleeve 301, the wastewater inside the sleeve 301 flows out from the through grooves, that is, the liquid inside the sleeve 301 flows out from the three through grooves respectively, and finally flows to the flotation tank through the gaps between the movable plate 307 and the collecting frame 308 on the adjusting component respectively, thereby realizing the dual functions of diversion and stirring, improving the distribution of bubbles in the flotation tank, and improving the combination effect of bubbles and suspended matter.
[0032] It is worth mentioning that an electrochemical sensor is provided on the electrode assembly 106. When impurities are attached to the surface of the electrode assembly 106, the resistance of the surface of the electrode assembly 106 increases, and the electrocatalytic efficiency is reduced, that is, the conductivity of the electrode assembly 106 decreases. The usage status of the electrode assembly 106 can be obtained through the detection result of the electrochemical sensor.
[0033] If the detection result of the electrochemical sensor shows that the conductivity of the electrode assembly 106 is within the standard range and the conductivity of the electrode assembly 106 is on a downward trend, it indicates that a small amount of impurities are adhered to the surface of the electrode assembly 106. At this time, the controller controls and adjusts the working state of one of the adjustment components on the surface of the sleeve 301. Specifically, the controller controls the hydraulic rod 306 to continue to contract, and the hydraulic rod 306 drives the movable plate 307 to move toward the direction close to the support plate 305, so that the movable plate 307 and the collection frame 308 are in a sealed state. In this process, the movable plate 307 and the push plate 309 The baffle 3012 is squeezed, the spring is stretched, and the opening between the baffle 3012 and the through groove on the sleeve 301 increases. At this time, part of the liquid inside the sleeve 301 enters the sealed cavity surrounded by the movable plate 307 and the collecting frame 308 from the opening between the baffle 3012 and the through groove on the sleeve 301, thereby increasing the amount of liquid entering the sleeve 301. Under the action of the liquid extraction tube 302, the flow rate of the liquid in the electrolytic cell entering the liquid inlet tube 303 is also increased, thereby enhancing the fluidity of the liquid at the position of the electrode assembly 106, and cleaning the impurities adhering to the electrode assembly 106 under the action of the water flow.
[0034] At the same time, the impact force of the liquid on the rotating blade 3042 increases, thereby increasing the rotation speed of the rotating blade 3042, so that the bubbles and suspended matter in the electrolytic cell can be stirred and broken, thereby increasing the contact area between the bubbles and the suspended matter, and also preventing the large volume of the suspended matter from affecting the normal operation of the liquid inlet pipe 303, and further preventing the suspended matter from accumulating at the bottom of the body 101 due to its excessive volume.
[0035] When it is necessary to clean the suspended matter accumulated at the bottom, the controller first controls the working state of another adjusting component on the surface of the sleeve 301. At this time, the three adjusting components on the surface of the sleeve 301 are in different working states. Specifically, the controller first controls the hydraulic rod 306 to extend, and the hydraulic rod 306 drives the movable plate 307 to move away from the support plate 305. At this time, the push plate 309 moves with the movable plate 307. Under the action of the spring, the baffle 3012 moves towards the direction close to the positioning plate 3011, so that the baffle 3012 can press the sleeve 3011. 01 is sealed. When the adjusting component rotates to the lowest point along with the sleeve 301, that is, the distance between the adjusting component and the bottom of the machine body 101 is the shortest, then the controller controls the hydraulic rod 306 to quickly contract, and the hydraulic rod 306 drives the movable plate 307 to move toward the direction close to the support plate 305, so that the movable plate 307 and the collection frame 308 are in a sealed state, and the hydraulic rod 306 drives the movable plate 307 and the push plate 309 to squeeze the baffle 3012, the spring is stretched, and the baffle 3012 is misaligned with the through slot on the sleeve 301. In this process, the movable plate 307 and the collection frame 308 are in a sealed state. The movable plate 307 drives the liquid at the bottom of the flotation tank and collects it into the sealed cavity surrounded by the movable plate 307 and the collection frame 308, and the suspended matter at the bottom of the flotation tank enters the sealed cavity surrounded by the movable plate 307 and the collection frame 308 along with the liquid, and then the liquid in the sealed cavity enters the interior of the sleeve 301 through the gap between the through groove and the baffle 3012, and the uncombined suspended matter at the bottom of the flotation tank and the new bubbles in the sleeve 301 are combined again, increasing the contact opportunity between the bubbles and the suspended matter, and then the wastewater inside the sleeve 301 is discharged from another regulating component position. The suspended matter flows out through the slot at the location where the water is placed, and finally flows into the flotation tank through the gap between the movable plate 307 and the collecting frame 308. The suspended matter after the secondary combination floats to the liquid surface under the action of the bubbles, which can significantly improve the flotation efficiency, so that more suspended matter at the bottom of the flotation tank can be adsorbed by the bubbles and float to the liquid surface to form scum, which can more effectively separate the suspended matter and impurities in the water, and also reduce the residue of uncombined suspended matter in the water, thereby improving the clarity and transparency of the water quality. In addition, the secondary combination process makes full use of the bubbles, reduces the waste of bubbles, and improves the utilization efficiency of resources.
[0036] It is worth noting that an angle sensor is provided on the driving shaft 3041 , and the rotation angle of the adjustment component at different positions of the sleeve 301 can be known through the angle sensor, thereby obtaining the position of the adjustment component.
[0037] By setting an electrochemical sensor to monitor the use status of the electrode assembly 106 in real time, the controller automatically adjusts the working status of the adjustment assembly according to the monitoring results, cleans impurities on the surface of the electrode assembly 106 in time, reduces corrosion and wear of the electrode assembly 106 by impurities, and extends the service life of the electrode assembly 106. By increasing the dissolved oxygen content of the wastewater and optimizing the flotation process, the rate of electrocatalytic oxidation is improved, the automatic control of the wastewater treatment process is realized, and the efficiency and stability of wastewater treatment are improved, thereby improving the activity of the electrode assembly 106, the combination effect of bubbles and suspended matter, the utilization efficiency of resources and the degree of automation of wastewater treatment. Through effective flotation and scraping processes, impurities and suspended matter in the wastewater are separated and collected, reducing the risk of secondary pollution, thereby significantly improving the overall effect of electrocatalytic oxidation treatment of high-salt industrial wastewater, and having significant creativity and practicality.
[0038] The present invention also provides a method for electrocatalytic oxidation treatment of high-salt industrial wastewater, and the specific method steps are as follows: S1: First, the wastewater to be treated is passed into the interior of the reaction component 1, and then the wastewater is electrolyzed by the electrode component 106 inside the body 101, and at the same time, the dissolved oxygen content of the wastewater is increased by setting the gas dissolving component 2 to improve the rate of electrocatalytic oxidation; S2: Then, the liquid treated by the electrode assembly 106 is diverted by setting a diversion assembly 3, and stirred during the diversion process, so as to improve the mixing reaction effect; S3: Finally, the bubbles generated during the electrolytic reaction of the electrode assembly 106 and the bubbles generated by the dissolved gas assembly 2 combine with the suspension in the wastewater and float to the liquid surface, and then the scum on the liquid surface is cleaned by the scraper 4 to separate the impurities in the wastewater.
